Fluid Treatment Apparatus

Abstract

A fluid treatment apparatus comprises a fluid inlet and a fluid outlet. A treatment chamber disposed between the fluid inlet and fluid outlet. A plurality of plate members are mounted in the treatment chamber. The plane of the plate members is orientated substantially in line with the direction of fluid flow through the chamber between the inlet and the outlet. The plates have at least one major surface comprising a photo catalyst. Irradiating means is provided for irradiating the photo catalytic surfaces with an activating radiation. In use the plates are rotated and the fluid is forced to flow between portions of the plates which are rotating against the direction of fluid flow. The rotation ensures that the photo catalytic surfaces of the plates are fully exposed to the activating radiation and also causes a turbulent fluid flow between the plates to ensure that any molecules in the fluid flow come into contact with the activated photo catalytic surfaces.
